Just to give the timeline, next anima step likely plays out the same as Midas did. Plus why 260 makes sense.

From week 1:
-i255 Sophia Extreme
-i260 A10S Micro tome drop + 1000 Scripture. Realistically the earliest they could be bought was first day of week 3.
-i270 A11S Gobdip upgrade drop
-i275 A12S drop

From week 6:
-i255 new PoTD. Another option for those that did not get a weapon from Sophia Extreme.
-i260 Anima. Those current with 240 step will get an opportunity to get an upgrade before those that don't have a current anima.

From week 7:
-i260 Free Alexander Micro-tome after 7 weeks of A12N + 1000 scripture, for those that don't raid Alex Savage or have an anima.
